[QUOTE="J E Custom, post: 135916, member: 2736"] No You would have to reach 3400 to 3500 fps before over rotation would occur. A 1 in 10 twist is very good in a 300win mag and will shoot the 220gr bullets well also. I have only had this problem once ,And it was a 32" 1in9 twist barreled 7STW with 120gr bullets exceeding 3800fps accuracy started going away at around 3700fps. You should be fine with 150 to 240 gr bullets, and your rifle will tell you which one it likes best. As the ausies say NO WORRIES MATE J E CUSTOM [/QUOTE]
